Introduction: Healthcare-associated infections (HAIs) are an infection that patients acquire during receiving treatment and care for the medical or surgical problem. Objective: The objective of this study is to find the patterns of HAIs cases in the hospital and to know the impact of the intervention on prevention and control of health care associated infection. Methodology: This was prospective interventional study. Results: The majority of cases of HAIs was reported from intensive care unit 47%. The most common site involved due to HAIs was catheter-associated urinary tract infection followed by central line-associated bloodstream infection. During the study period, around 28% reduction of cases were reported. During 6 months period (March to August 2016), around 540 cases were admitted in the critical care areas out of that 32 cases were reported as HAIs (5.9%) for the same period from (March to August 2017) was (3.4%), that difference came to be a statistically significant (χ2 = 4.12, P = 0.042, df = 1). Conclusion: This small study showed that strict implementation of care bundles with good compliance of hand hygiene, Personal protective equipment and antibiotic stewardship are helpful for prevention and control of hospital acquired infections. This study also demonstrated significant (28%) reduction of hospital acquired infections during the study period.

Healthcare-associated infections (HAIs) is an infection that patients acquire during receiving treatment and care for the medical or surgical problem.[1] HAI is a major concern for patient safety and its can lead to a prolonged hospital stay, long-term disability, the resistance of microorganisms, the extra financial burden to the healthcare system, more costs for patients and their families, and increases mortality.[2],[3] HAI is defined as: “An infection occurred in a patient during the process of care in a hospital or other health-care institution which was not present or incubating at the time of admission. This includes infections acquired in the hospital but appearing after discharge.[4] The CDC and WHO surveys conducted in the 183 hospitals in the United States of America and observed 4% HAIs, the most common types were pneumonia (21.8%), followed by surgical site infections (21.8%), and gastrointestinal infections (17.1%).[5] The study conducted by Moataz M. et al. in 2004 at Saudi Arabia about surveillance of nosocomial infections in the military hospital they observed 32.3% respiratory tract infection followed by 25.7% urinary tract infection (UTI) and 18.6% bloodstream infection (BSI).[6] We estimated that in 2011 there were 648,000 patients reported 721,800 HAIs in U. S. acute care hospitals. On these HAIs cases, 33,848 pathogens reported, 87% were bacteria, and 13% were fungi.[6] Over 15% of infections were polymicrobial. The most commonly isolated pathogens were coagulase-negative staphylococci aureus, Enterococcus species, Candida species, Escherichia More Details coli, and Pseudomonas aeruginosa.[7] In Europe, 5 million HAIs cases reported every year, of which 50,000 (1%) are lethal and contribute to death in 135,000 cases (2.7%).[8],[9]

Objectives

The aim of this study is to find out the patterns of HAIs cases in the hospital and to know the impact of the intervention.

» Methodology

A prospective intervention study was carried out for 6 months from March to August 2017, for the control of HAI in the hospital, the following intervention was done for the prevention and control of HAIs.

No sampling technique was applied all patients admitted in hospital during the study period were applied all interventions and reported. HAIs cases during the study period were taken as a sample for the comparison.

A bundle is a set of evidence-based practices that, when performed collectively and reliably, improve patient outcomes. Many bundle elements are well-established practices, combined in a structured protocol that is agreed on and is the responsibility of the whole clinical team.

Components of care bundles

Ventilator-associated pneumonia bundle (VAP Bundle).

Head elevation 30-45 degree. It helpful in preventing mucus collection and blockage of tube. This also increases the mucus drainage by gravity

Daily assessment of readiness to extubate

Daily oral care (chlorhexidine mouthwash)

Sedation vacation

VTE prophylaxis

Peptic ulcer disease prophylaxis

Keep the ventilator circuit free from condensation on every 2–4 h

Use meticulous hand hygiene before and after contact with ventilator circuits

Change inline suction catheter system only when soiled or every 72 h

Store oral suction device in a clean nonsealed plastic bag when not in use.

Catheter-associated urinary tract infection bundle

Hand hygiene and proper use of personal protective equipment's

Aseptic insertion techniques single use of lubricant sterile jelly

Meatus cleaning

Empty urine bag before three fourth fill

Urinary catheter bag hanging below the level of the bladder and not touching the floor

Urinary catheter has been continuously connected to a closed drainage system

Empty urinary catheter bag as a separate procedure into a clean container

Daily assessment of catheter requirement or need.

Central line-associated bloodstream infection bundle

Hand hygiene before touching the site

Daily inspection of the catheter

Port entry maintain closed all the time

Swab the diaphragm of the port with alcohol before using

Daily assessment of the possibility of removal.

Antibiotics stewardship program implementation.

The HAI data were compared with the same period of the previous year (2016), for that monthly data were collected for HAIs for 6 months during the study period (March–August 2017).

Collected data were entered in excel sheet and analyzed with the help of SPSS 20 (develop by IBM, USA), Value of P ≤ 0.05 considered to be statistically significant.

Data were presented in the form of tables and graphs.

» Results

[Table 1] shows that the majority of cases of HAIs reported from intensive care unit 47% followed by male medical wards 22%, major reduction of cases shown in the medical department 50% due to intervention. [Table 2] shows the most common site involved due to HAI was catheter-associated UTI (CAUTI) followed by central line-associated BSI (CLABSI). [Graph 1] shows that during the study period around 28% reduction of cases were reported; [Graph 2] shows a major reduction of cases in July 66%. During 6 months (March to August 2016), around 540 cases were admitted in the critical care areas out of that 32 cases reported as HAIs (5.9%) for the same period (March to August 2017) after the intervention around 680 cases were admitted in critical care areas out of the 23 cases reported as a HAIs (3.4%), that difference came to be a statistically significant (χ2 = 4.12, P = 0.042, df = 1).

Table 1: Distribution of healthcare-associated infections cases in the various departments

If we compared data between pre- and post-intervention regarding HAI cases according to department and statistical test was applied no statistically significant difference were observed (χ2 = 2.49, P = 0.777, df = 5), data also compared between pre- and post-intervention regarding types of HAI according to site of involvement and statistical test was applied no statistically significant difference was observed (χ2 = 4.73, P = 0.449, df = 5).

» Discussion

This present intervention study was carried out to control of HAIs in the hospital, from March to August 2017. The intervention studies conducted by Abdraboh et al. regarding hand hygiene and HAI they found postintervention, significantly improvement in the knowledge and compliance results reduction of HAIs cases in the hospital.[10]

Cochrane review done by Gould DJ and others about intervention study to improve hand hygiene compliance in patient care. However, this systematic review found that only a few high-quality, generalizable studies addressing the issue, in the present study, we also implemented stickt hand hygiene in critical areas.[11]

The systemic review done by Silvestri L et al. regarding Adult Hospital and Ventilator-associated Pneumonia Guidelines: Eminence-rather than Evidence-based, author mention many lacuna in the ATS/IDSA guidelines for control of VAP not considering many facts, in the present study, we implemented evidence-based preventive care bundles and other intervention for prevention and control of HAIs in critical area.[12]

» Conclusion

The present study showed that strict implementation of care bundles with good compliance of hand hygiene, personal protective equipment, and antibiotics stewardship is helpful for prevention and control of hospital acquired infections. This study also revealed statistically significant (28%) reduction of HAIs cases during the study period.
